I need to produce some plots that look like these but I'm not sure what they are called in mathematica, can anyone identify them ?
Update: I want to plot triples of the form (xvalue, yvalue, intensity) in a graph like that
It might be ListDensityPlot with an InterpolationOrder of 0 and a black/white ColorFunction
DensityPlot
! $\endgroup$ArrayPlot
. There's also MatrixPlot, Image, Graphics[Raster[...]], and ListDensityPlot (which can interpolate). For triples you need ListDensityPlot or see this $\endgroup$
